Publication number: 20030006171Abstract: A method and apparatus for testing the segregation of particulate materials includes a shear cell having a top, side, and bottom walls. The shear cell is between two stationary walls in a frame and includes a cam pin which rides on top of a cam connected to a rotating motor. A collection tray, including load cells, is placed beneath the perforated bottom wall of the shear cell. Large particles are placed in the shear cell and data collection is begun. Small particles are placed on top of the larger particles and the shear cell is closed. The motor is then turned on, applying strain at a certain strain rate to the particles within the shear cell. The smaller particles percolate through the larger particles and through the perforated bottom wall into the collection tray. Load cells in the collection tray transmit data to a computer for analysis.Type: ApplicationFiled: July 6, 2001Publication date: January 9, 2003Inventors: Virendra M. Puri, Shawn P. Duffy
